Carnival of Mathematics – First Anniversary Edition
It’s over at 360.
It opens with a brief discourse on the number 26 (this is also the 26th edition), but ponder, for a moment, that 360 instead. Days in a year (almost). Seconds in an hour. Degrees in a circle. 
And a Carnival of Mathematics that will likely never happen. Technology, media, change too fast. It is inconceivable that the Carnival will be around in this form for number 360. But you can bank on 36 in a few months.
My favorite new-for-me post is Mark Dominus’ famous mathematical goof post (showing that even mathematicians forget to consider all cases from time to time; and also showing that sometimes just because someone is famous, that doesn’t mean they are always right).
A commenter, Kaz, has a post on Peano and poetry. I would command you to go look, but I can’t. So I urge you to examine the post wherein the author, using only 5 simple postulates, proves that no cat is the god of itself.
